Well here is my php code, yes it has tabs so it will mess up here but the code is fine, the bottom regexp replacements for the url both work, its the top eight that return errors.

 

Submitting Message...

this is a pattern error, enclose all of your patterns with "/ -pattern- /" and make sure to escape any / (forward slashes) in your pattern.

 

 

eg:

	$_POST['message'] = preg_replace("/\[b\](.+?)\[\/b\]/",
	" <strong>$1</strong>", $_POST['message']);

$_POST['message'] = preg_replace("/\[i\](.+?)\[\/i\]/",
	" <em>$1</em>", $_POST['message']);

$_POST['message'] = preg_replace("/\[u\](.+?)\[\/u\]/",
	" <u>$1</u>", $_POST['message']);

 

hope this helps,
